Chrysanthemum plant named ‘Yellow Yodurango’

ABSTRACT

A new  Chrysanthemum  plant named ‘Yellow Yodurango’ particularly distinguished by the yellow ray floret color, decorative type semi-double flowers, strong stems, good shelf-life, dark green foliage, uniform plant habit and flowering response time, and about an 9-10 week flowering response time.

Latin name of the genus and species of the plant claimed:Chrysanthemum×morifolium.

Varietal denomination: ‘Yellow Yodurango’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically knownas Chrysanthemum×morifolium, and hereinafter referred to by the varietyname ‘Yellow Yodurango’.

‘Yellow Yodurango’ is a product of a planned breeding program. The newcultivar has yellow ray floret color, decorative type semi-doubleflower, strong stems, good shelf-life, dark green foliage, uniform planthabit and flowering response time, and about an 9-10 week floweringresponse time.

‘Yellow Yodurango’ originates as a natural whole plant mutation of‘Yodurango’, U.S. Plant Pat. No. 19,736. ‘Yellow Yodurango’ wasdiscovered and selected by the inventor as a single flowering plantwithin a population of the parent cultivar in a controlled breedingprogram in Fort Myers, Fla. in February 2007. The parent cultivar‘Yodurango’ has orange-bronze flower color.

The first act of asexual reproduction of ‘Yellow Yodurango’ wasaccomplished when vegetative cuttings were propagated from the initialselection in May 2007 in a controlled environment in Fort Myers, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plantinitiated in May 2007, and continuing thereafter, has demonstrated thatthe combination of characteristics as herein disclosed for ‘YellowYodurango’ are firmly fixed and are retained through successivegenerations of asexual reproduction.

‘Yellow Yodurango’ has not been observed under all possibleenvironmental conditions. The phenotype may vary significantly withvariations in environment such as temperature, light intensity and daylength.

A Plant Breeder's Right for this cultivar was applied for in CPVO onJun. 25, 2009 (#2009/1161). ‘Yellow Yodurango’ has not been madepublicly available more than one year prior to the filing of thisapplication.

The following traits have been repeatedly observed and are determined tobe basic characteristics of the new variety. The combination of thesecharacteristics distinguishes this Chrysanthemum as a new and distinctvariety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliagecharacteristics of ‘Yellow Yodurango’ with colors being as true aspossible with an illustration of this type. The photographic drawingshows 4 flowering potted plants of the new variety growing in a 5½ inchpot and a close-up of the flowers.

DETAILED BOTANICAL DESCRIPTION

The plant descriptions, measurements and aforementioned photographs weretaken in Gilroy, Calif. in June 2010 under natural light. These plantswere started and grown in Nipomo, Calif. and were shipped to Gilroy inJune. Plants were grown under conditions which approximate thosegenerally used in commercial potted Chrysanthemum production. Theseplants used in the photograph and descriptions were about 10 weeks old.

Color references are made to The Royal Horticultural Society ColourChart (R.H.S.) 2001.
